To all the people who are making fun of OP for saying he wants "a bottle". I am a senior in high school and this is actually a normal thing to say. "Ey man would you put up for a bottle" Times change, so does slang
Also OP, last resort you can always steal a bottle. Its kinda sketchy so don't do it too often and test your luck.
But in a clutch time, just walk into the store, pick up desired alcohol and walk out the door. 9/10 times they won't even notice. They'll assume you bought it. If the happen to notice they probably won't do anything. If they do just run. They will not chase you. That's a fact.
IF you choose this method, be careful.
